FAQ: Q: Can you make custom lightweight pulleys for any application?A: Almost! We are one of very few companies with 15+ years of experience in this field.

Q: Can I send you measurements or do I have to send you my OEM pulleys?A: In many cases we already have engineering data based on past experience and you can provide custom sizes for a quote, but we will need you to send in OEM pulleys if/when we do not have existing data.

Q: Do custom pulleys take long to manufacture?A: Do to the nature of the beast here, and several external factors, custom pulleys can require 30-40 days to machine, anodize, and ship. Please don't wait till the last minute if you know your project is time sensitive.

Q: Are custom pulley kits expensive?A: We do our best to keep prices as affordable as possible, you can browse our website for an idea of what most our kits cost, of course custom one-off products always cost more. Feel free to email us for a quote and we'd be happy to do our best to help.

Q: Which custom pulleys are the most popular and why?A: Supercharger pulleys are the most popular of all the custom pulleys we offer, because changing the size of a supercharger pulley directly affects boost/psi numbers, we also offer a larger number of lightweight crank, alternator, water pump, and power steering pulleys. All of these pulleys are very popular because the weight reduction (NST Pulleys are apx 70% lighter than OEM) leads to improved throttle response, better horsepower and torque delivery to the wheels, and better fuel economy.
